D. Malesani (SISSA/ISAS), P. Jakobsson (U. Hertfordshire), J. Fynbo, M.
Stritzinger (DARK, NBI), and S. Covino (INAF/OABr), report:
We observed the field of GRB 060719 (Stanatikos et al., GCN 5339) with
the ESO VLT + ISAAC, starting on 2006 Jul 19.4237 UT (3.3 hr after the
trigger). Images in the Js, H and Ks filters were acquired.
The three objects close to the XRT position reported by Berger & Bonanos
(GCN 5340) and Fugazza et al. (GCN 5347) are detected in our images. We
note that object #1 of Fugazza et al. (GCN 5347) is significantly
outside the revised XRT position (Conciatore et al., GCN 5348), while
object #2 is still at the border of the 90% error circle.
Object #2 is very red, as observed in KHJ images: it is well detected in
Ks and barely visible in J. Compared with the R-band measurement (which,
we caution, was taken at a significantly earlier epoch; GCN 5347), it
has a color R-K ~ 4.5 +- 0.2. At this stage, we cannot assess, however,
whether this object is related to the GRB.
